[origin: US5714016A] PCT No. PCT/JP93/01385 Sec. 371 Date May 25, 1994 Sec. 102(e) Date May 25, 1994 PCT Filed Sep. 29, 1993 PCT Pub. No. WO94/07630 PCT Pub. Date Apr. 14, 1994A gear for wheel speed detection or sensor ring has a low cost and an excellent corrosion resistance. The sensor ring is mainly made of sintered stainless steel. A surface layer of the sensor ring contains at least 5 atomic % and not more than 25 atomic % of phosphorus, at least 30 atomic % and not more than 70 atomic % of oxygen, and at least 5 atomic % and not more than 50 atomic % of iron, and at least partially consists of an amorphous phase. The surface layer is formed by dipping a sintered stainless steel product in oil at a temperature of 15 DEG to 70 DEG C. containing phosphoric acid groups.
